Compressed air blasting is a fast and thorough method to remove marine growth, paint and corrosion. It’s the perfect pre-treatment for inspection jobs but can also leave a SA2½ finish for repainting. It’s a silent and safe method without the need of retro jets.
The diver will be the actual blaster, holding the nozzle and preparing the surface. The start/stop of the machine and controls etc. will be done by the operator at shore.
After the vessel is filled with abrasive it is pressurized first by the operator to put it in stand-by mode. This is done by a switch on the control box.
On the control box also the blasting pressure can be set by the operator.
When the diver is ready the start/stop of blasting is controlled by the operator with a switch on the control box. The blasting air valve is opened together with the abrasive metering valve after which the operator can set the correct amount of abrasive for the application.
